JOSEPH KAHN, OF CHICAGO, ILLINOIS.

LOOSE-LEAF BINDER.

Application filed May 1,

To all whom it may concern:

Be it known that I, JOSEPH KAHN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Loose- Leaf Binder; and I do hereby declare that the following is a full, clear, and exact de scription of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to loose leaf binders in which the impaling posts are hingedly connected to the cover, and primarily consists of certain novel improvements in actuating and locking means for the shiftable hinge members which connect the impaling posts to the cover.

This application is a continuation in part of my application for loose leaf binder, Serial No. 428,182, filed December 4th, 1920, as to that matter common to both.

This invention comprises the novel mechanism and combination hereinafter described and more particularly pointed out anddefined in the appended claims.

In the accompanying drawings, which illustrate a preferred embodiment of this invention, and in which similar reference numerals refer to similar features in the different views:

Figure 1 is a fragmentary'plan view of the interior of the binder illustrating one position of the hinge members, with parts removed.

Figure 14 is a cross sectional view of the binder shown in Figure 13.

Figure 15 is a section through the back of the binder showing the plan view of the leaves and posts extending therethrough.

Figure 16 is a cross section of a modified form of binder.

As shown on the drawings:

In referring to Figures 1 to 10, which i1- lustrate one embodiment of this invention, the reference numerals 1 and 1 represent the side covers of the binder which are hinged to the vertical clamping members 2 and 3- 0f the back of the binder, preferably by means of the fabric covering thereof, the member 3 being higher than the member 2. The clamping members 2 and 3 may be held in spaced relation by a rear member enclosed in suitable fabric that also covers the clamping members 2 and 3, or the clamping members may terminate in right angles overlapping parts for securing adjustability of the binder as shown in Figure 5. lVhere the adjustable binder is used, it will of course be necessary to use plan view of a such sectional posts as are shown in Figure 5. However, these binder covers and sectional posts are old and well known in the art and form no part of this invention except in so far as they are modified or 00- operate therewith.

According to this invention a plurality of spaced leaf holding posts 5, two in the present instance, span the rear portionof the binder. While these posts may be hingedly connected to both covers, the preferable construction consists in providing heads 6 (Figure 4) on one end of the posts and making the clamping members of unequal height and anchoring the headed end in the higher clamping member of the binder.

This may be accomplished by providing proper recesses in the upper margin of the clamping member 3 to receive said heads and extendingapertures therethroughto re ceive said'posts 5 in a horizontal axial'plane above the top'of the clamping member 2 as shown in Figure 4.

The opposite or projecting ends of the posts 5 are bifurcated, and links 7 are pivoted in these bifurcated portions- The. free ends of said links are providedwith eyes 8 and are adapted, to passbetween apertured lugs 10lprojecting; from a hinge plate 11 which is inset in the inner margin. ofthe adjacent cover 1 the eyes 8. being. adapted to be brought. into registry withthe apertures in the legs, so that the hooked ends of the swingable hinge member 9. pivoted on the hinge plate ll may pass through the. aperturesinlugs10-andeyes 8 for hingedly connecting the posts to thesaid adjacent cover.

The. hinge members. 9. areadapted to. be operated by actuatorszwhich are in. the form of. levers 12 pivoted intermediate their ends to the plate 11 adjacent said members 9. The; inneror. weight. arms of; said levers 12 extend overthe hinge membersf9, and the ends thereof. are provided. with. downwardly en ng; l gs 13. (Fi adapted to gage the hinge members 9 andswing them into inoperative position, as shown-in Figure 2, when the leversv are swung in proper directions. arms adjacent the pivot fulcrumsare providedwith cam-portions=11 3), shown alsoindotted lines in Figures 1 and 2, which are adaptedto. contact the outer sides of the hinge-members; and: swing them into operative'position in. engagement with the lugs 10and.links. 7 when said levers are swung from the positions; showndn Fig. 2 to the positions shown in. Fig. 1.

Mechanism 1 has been provided for locking the impa-ling posts; to. the cover which is hinged: thereto, and while this mechanism may take variousforms, the illustrated mechanismi comprises.- rotatable abutments 15 securedupon studs16. which are provided with polygonal shaped heads or upper ends (Fig.8.) for. receiving. awrench or the like whereby. they may be rotated for rotating the abutments into-the paths of the levers 12, as shown in Figure 6, to prevent further movement. of said levers. Each abutment is normally retained in the position illustrated in: Figures. 1 and 2,. in which a projecting tailpiece 17 coacts with astud projecting from; the: plate. 11 for preventing. improper rotation of the abutment. When the abuts ments are properly. rotated intothe path or the levers 12, they are arrested. at a predetermined point by. means of stops 18 which are in the form of pins or studs projecting from the plate: 11, as shown in Figure 6, so that when the levers 12 are swung to disengage The inner ends of said weightare retained on the posts proper.

the hinge members 9, they will strike the arrested abutment 15 and be held from further movement in the direction to release the hinge members. It will be noted that the stops 18 are so positioned that they pass between the lugs 13 and cam surfaces 14; of the levers duringthe operation of the levers to release the hinge members 9.

As previously mentioned, the plate 11 is inset in the inner margin of the cover so that the parts mounted thereon may be concealed by a cover 19 having side flanges resting upon the plate 11, the side flanges being provided with depending lugs or tongues 20 (Fig. 10) adapted to lit in sockets 21 formed in the marginal side edges of the plate 11, and the cover 19 being secured in position-by a single screw 22 and the inner flange being cut away to accommodate the hinge members 9 and levers 12. As shown in Figure 8, the plate 19 is provided with apertures into which the polygonal heads of the studs 16-project so that they may be.en gagedby a wrench or the like, and the said plate 19 is shorter than the plate 11 leaving a space at each end into which the power arms or handle portions oithe'actuators 12 project so that they may be accessible for operation.

In Figures viously described structure in the'omission otihe levers 12, the-locking abutments 15 and the cover plate 19 and providing single hinge lugs on the plate 11, and the addition of guides 23 having stop lugs at each end to limit the swing of the hinge members 9 which normally rest between said stop lugs.

In the form shown in Figures 1 to 12, the leaves that are retained on the links 7 'may shift longitudinally and become slightly oiiset with respect to the other leaves which In order to prevent this, medial posts 5 may extend from the clamping member 3 for. receiving 11 and 12, a modification has l been illustrated which differs from thepre- Hit) the leaves and preventing the disarrangement or offsetting thereof. 7

in Figures 18, 1a and 15, I have illus trated a slightly modified form or binder in which cylindrical iinpaling'posts are so constructed and arranged that relative longitudinal shifting of theleaves 2 1 is, prevented. In this modifiedit'orm, the end posts 25, which are secured to the clamping member 3 at their headed end, have. their tree ends mortised on their outwardly directed sides for receiving the hinge lugs 26 on the hinge plate 27 secured to the inner side of the c0ver 1. Bymortising the end posts 25 upon their outwardly directed sides, the inwardly directed sides remain full, as shown in Fig. 15, and as these full or unmortisedsides extend in opposite directions, they will combine to prevent the loose leaves 24; from being shifted in either longitudinal direction as is obvious from an inspection of Fig. 15. The mortised ends of the posts 25 and the lugs 26 have registering apertures for receiving the pivoted and swingable hinge hooks 9, as described in connection with the other forms.

In this form of the invention, a medial impaling post 28 extends from the clamping member 3 and is provided with a tenon upon its free end which fits between a pair of hinge lugs 29 on the plate 27. ihe tenon and hinge lugs 29 have registering apertures for receiving the pivoted and swingable hinge hook 9, which is adapted to be actuated by an actuating lever 12 similar to the one shown in Fig. 1. A shiftable abutment corresponding to the abutment 15 mounted upon a pin 16 serves to lock the actuator 12 as in the first described form, the parts being covered by a plate 30, only the handle of lever 12 and pin 16 being shown.

Fig. 16 illustrates a slightly different way of anchoring the impaling posts to the side 3 of the binder. In this form, the impaling posts have conical heads fitting in countersunk apertures in ametal strip 3 inset in the inner face of the clamping member 3 and secured thereto, the clamping member 3 being higher than the clamping member 2 as in the other forms so that the impaling posts lie in a plane above the clamping member 2 whereby their free ends may be hinged to the cover 1.

In the use of a binder involving this invention, loose leaves 24 properly punched are adapted to be retained on the impaling posts 5. When it is desired to add additional leaves to the binder the hinge members 9 are swung out of operative engagement with the posts 5, as previously described, whereby the clamping member 2 is disengaged from the posts 5 and may be shifted or swung outwardly or downwardly so that loose leaves may be readily impaled upon the posts. The binder is again assembled by bringing the hinge lugs on the plate 11 into registry with the links in the posts 5 and swinging the hinge members to engage the same as is obvious.

I am aware that numerous details of this invention may be varied through a wide range without departing from the principles of this invention, and I do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:
